I hate those 10:00 PM quiet time rules.
Here on the western edge of the Atlantic time zone the sun does not set until around 9:30 PM and it is not even dark at 10:00 PM from mid-June till early July. Often don't even light the campfire until about 9:30 in the early summer!
At 10:00 PM people are still out walking around, kids are playing and the night is young!
Sure would hate to have the host telling me to put out my fire and go inside my rig while it is still light enough to read the paper outside!
I guess that is why many campgrounds up here have 11:00 or 12:00 PM quiet time rules.
